The switch was expected after veteran Sam Baker went down with a season-ending knee injury in Saturday’s preseason game against the Houston Texans. He was placed on injured reserve Monday.

Matthews, the No. 6 overall pick in the 2014 NFL Draft, played left tackle for one year at Texas A&M after being on the right side. He said it’s an adjustment to switch positions.

Lamar Holmes took over for Matthews at right tackle during Monday’s practice in Flowery Branch, Ga.

Minnesota Vikings coach Mike Zimmer confirmed, as expected, that quarterback Matt Cassel will make his third straight preseason start Saturday at Kansas City.

Although Zimmer has yet to name the starter for the Sept. 7 regular-season opener, Cassel will be under center barring injury when the Vikings travel to St. Louis.

Cassel, who is competing with rookie Teddy Bridgewater, hit 12 of 16 passes for 153 yards and a touchdown and added 30 rushing yards in last Saturday’s 30-28 win over the Arizona Cardinals.

The return of Kansas City Chiefs running back Jamaal Charles from a fluke injury is not yet known after a bruised foot kept him out of Sunday’s preseason game against the Carolina Panthers.

Charles was injured Thursday when he took a misstep over a curb while moving out of the dorms at Western Missouri at the end of the Chiefs’ training camp.

Kansas City coach Andy Reid said Monday that X-rays and an MRI show no major injury.

The Carolina Panthers’ most-important moments Sunday night had nothing to do with a completion, an interception, or even a touchdown. Instead, they were three plays that went for minus-19 yards.

Playing in his first game on a surgically repaired ankle, quarterback Cam Newton scrambled three times. The results were an incompletion and two sacks. It’s not a good look in the box score, but those plays were ultimately successful. Newton’s ankle passed its first real test.

New York Jets rookie wide receiver Jalen Saunders returned to the team’s practice facility, three days after he had a “medical event” while driving his car.

New Orleans Saints tight end Jimmy Graham said he understands - get the points, not the penalties.

Graham said he will no longer dunk to celebrate touchdown receptions, which became part of the former college basketball player’s routine during his rookie season, and for most of his 41 scores.

But with the offseason rule change that penalizes players for “dunking” the ball over the goalpost, Graham drew two penalties and the ire of head coach Sean Payton during Friday’s preseason game.
